To be honest, Yevgeny doesn't like China very much.

He had been to this country when he was young, and in his memory, the Chinese were a very shrewd people, so shrewd that many of them could not stand it.

Yevgeny still remembers that when he came to China, Russia was in the most difficult time in history, and the Chinese shipped them a large amount of inferior and fake wine, artificial leather coats, and down jackets made of stinky chicken feathers However, what was replaced was a brand new machine tool, drawings and related engineering personnel.

Yevgeny came to work in China during that time.However, he didn't stay for long. A year and a half later, he went to the United States through a friend's introduction. Since then, he has stayed in a university as a professor until now.

Yevgeny’s impression of China is still his own experience when he was young, and most of the most profound ones are Chinese baijiu.

From bulk sorghum liquor sold in grain and oil stores, to Wuliangye and Moutai in hotels and restaurants... To be honest, in Yevgeny’s opinion, none of them are as good as Russian vodka. Chinese people believe that different liquors have different flavors, so these liquors are combined It always tastes a little weird—this wine is just like Chinese characters, Chinese dishes, and Chinese characters, complex and changeable.

Yevgeny didn't like complexity, and almost every Russian he knew didn't like complexity.

But now, Yevgeny felt that his future life might never be simple again.

This feeling reached its peak when Yevgeny woke up and confirmed that he could not feel gravity.

Yevgeny didn't know what this place was. There was no gravity environment. With Yevgeny's knowledge, there were only two possibilities.Either he's in a giant, crashing giant house right now, or he's in some space station in Earth orbit right now.

But after following Shen Changwen and simply turning around here twice, Yevgeny knew that neither of these two possibilities was possible-the earth cannot build such a large space station now.

Yevgeny could see subtitles on the wall, in Chinese and Russian.

Yevgeny was inexplicably surprised by this discovery—he almost began to wonder if China and Russia secretly excavated and built a lunar base on the moon without telling all the people on Earth.He once watched a movie with a similar plot, saying that the Nazis after World War II did not die out, but continued to develop on the far side of the moon, preparing to make a comeback.

Now, the subconscious association brought to him by this space station is this plot.Maybe the USSR didn't collapse and they're still here to continue...

But Yevgeny soon learned that this idea was wrong.

"We still need propellant, even the simplest propellant," Shen Changwen brought him in this time because of this technical problem, "but the original fuel chamber is too small, so we need to temporarily enlarge it."

In front of Yevgeny were the two nuclear warheads that he saw with his own eyes, salvaged from the bottom of the Pacific Ocean, and now placed side by side in front of him.

The missile fuel tanks have all been dismantled, and the original nuclear warhead explosives have been removed, replaced with detonators redesigned by Yevgeny.

Because of the changes in the explosive formula and the need for an additional insurance factor, the newly installed explosives were much larger than the original nuclear warhead, which turned the originally slender conical warhead into a flat spherical shape, which looked very ugly.

If this kind of nuclear bomb is put back on the earth and the photos are shown to others, people will definitely be laughed to death, because this image plus the original cylindrical fuel tank, the overall shape looks like a male genitalia.This huge mass and ugly shape also determine that it is difficult for these two "missiles" to escape the gravity of the earth for projection.

From Yevgeny's professional perspective, these two missiles can no longer be called missiles after being "rebuilt" this time, and they may be regarded as two nuclear landmines.

If it was on the earth, Yevgeny would definitely laugh wantonly when he heard Shen Changwen's request now, because as far as the fuel chamber of a missile, or the propulsion department is concerned, the size and regulation are quite restricted. Many factors limit, the most important of which is the warhead.

When Shen Changwen asked him to design the warhead before, the design requirement he put forward was-as long as it can guarantee the explosion, it can be of any shape.And now, it is necessary to temporarily increase the propulsion department, which is like asking a tailor to make a coat for a fat man, and then pull a thin man to make pants, and require the two clothes to match.

In Yevgeny's view, this contradiction could not be completely resolved. After he saw the space station, he was completely relieved.

On the way all the way, in fact, he has figured out all the technical issues.

Shen Changwen's request is completely achievable and very easy.

In a zero-gravity environment, if you want to make a "missile", you only need to maintain the most basic moment, that is, don't let the missile itself flip over due to the propulsion force in the air, and that's enough.

This is not like on the earth, because of the existence of a gravitational field, the design requirements for propellers are very high-in most countries, the technological content of making missiles exceeds that of making nuclear bombs.

What is difficult about nuclear bombs is the process of accumulating experience. The principle is known to the whole world. With modern technology, even if it is a miniaturized design, it can go through several test explosions and then simulate it all on a computer.

But the design of the missile itself is much more complicated, especially for nuclear missiles that require very high reliability, navigation attitude control, fuel control, maintenance, launch platform...

Yevgeny once knew a missile expert who once described the difficulty of designing a nuclear missile—a designer who had to assume that he was a fat man who was good at mathematics and jumped from the top of the Empire State Building in New York after eating a lot of beans. .

In this process, it is necessary to accurately calculate the biochemical reaction rate of the bean in the intestinal tract so that it can always discharge gas evenly.

Fat people need to adjust their posture at any time in mid-air. If the limbs are far from enough, some special auxiliary clothing should be prepared to generate a suitable lift.

Of course, these are not the most important. The most important point is that during the whole falling process, the fat man's own mental state must be guaranteed to be stable, so as not to let him pee out of fear in advance.

But if the environment is changed from the Empire State Building in New York to the Mir space station, then this task will undoubtedly be much simpler.

"Also," Shen Changwen added a request, "The strength of the outer shell needs to be strengthened."

"The strength of the shell?" Yevgeny was sensitively aware of something, "There will be interception? Is it the laser weapon you mentioned?"

Before coming here, Shen Changwen had actually explained most of the design requirements, but because Yevgeny really couldn't imagine the specific requirements he needed, and finally after comprehensive consideration, he decided to use the original sleeping pill delivery Form, brought him into the space station.

"Yes," Shen Changwen raised a stick-like thing from his hand, handed it to Yevgeny, took it back, pointed the stick at a standard tank composite armor plate, and said to him, "It's a demo where we step back and put the goggles on."

This composite armor plate was brought out by Shen Changwen from his laboratory, and he had shown it to Yevgeny before coming here.This is the armor material used on modern mainstream tanks. In terms of protection alone, it is already the most cutting-edge technology on earth.The armor plate in front of them is a full 30 centimeters thick, which is equivalent to the thickness of the side armor of a mainstream medium tank.

The so-called laser weapon in Shen Changwen's hands was something Yevgeny had never seen before.Just when Yevgeny was still wondering how the laser emitter should emit laser light, Shen Changwen turned on the switch.

A red beam of light appeared, because the air here is very clean, so it is not very clear.But the effect on the target, that is, that piece of armor, is very clear and obvious.The armor almost produced material vaporization at a visible speed, and a small black hole quickly appeared at the position of the light spot.This process lasted for a full 12 seconds. After 12 seconds, the black hole became transparent—the armor had been completely penetrated.

"The weapons we need to face will be hundreds of times more powerful than this laser launcher."

Yevgeny stepped forward, took back the armor plate, put it in front of him, and observed with his own eyes the hole that had just been burnt out.

There is hardly any change in the temperature of the material itself. On the one hand, it is because the heat transfer rate of the material itself is not fast. On the other hand, it is enough to explain the power of this laser weapon.

Yevgeny had only heard in newspapers and novels that China and the United States might be developing laser weapons—he never expected that they would be able to achieve this level.

Looking at the laser emitter again, it's just a half-meter-long tube, not much longer than an ordinary rifle, and the complicated structure of the rifle can't even be seen.

If the tube in front of you is called a laser gun, then the one described by Shen Changwen, with hundreds of times the energy, can undoubtedly be called a laser gun.

Countless thoughts flashed in Yevgeny's mind, China, the United States, orbit, the moon, space operations... Could it be that the earth he is familiar with is an illusion?The real US and China are now competing for space?Fighting with laser guns and laser cannons?

"Don't think about it," Shen Changwen could see that Yevgeny's mind was distracted, indeed, no one could maintain his composure after entering this space station, "What we have to leave now is to quickly come up with some feasible solutions. This energy level should be difficult to achieve in terms of protection."

Although Yevgeny's mind was messed up, what he said was still very professional: "If it's just this kind of laser weapon, theoretically it won't affect the operation of the nuclear bomb itself. The stability of the weapon is very important to the temperature. Not sensitive, the only thing worth worrying about is the propellant... If it is intercepted by this kind of laser, the effect of strengthening the shell will not be too obvious. On the contrary, it will greatly increase the weight of the missile and slow down the speed. For laser weapons, Low speed means longer aiming time at the same time - so if you want to protect this kind of laser, the best way is to speed up..."
